President’s Message

I am greatly honored to serve as LIA President for 2016. Having been involved in LIA activities since 1986, I have witnessed the growth and changes of LIA over the last 30 years. ICALEO® has grown from traditional macro-processing to wider themes including micro and nano-fabrication, additive manufacturing and the introduction of peer-reviewed papers for publication in the LIA journal, Journal of Laser Applications® (JLA), which has seen a noteable improvement in quality, scientific impacts and citations over the last few years. The development of high power fiber lasers and ultra-fast lasers over the last decade has changed the entire laser processing industry. I am grateful for the leadership and hard work by Past President Robert Thomas, LIA Executive Director Peter Baker, all the LIA past presidents, the LIA staff and our Board of Directors over the last few years to develop and drive LIA agendas to promote laser and photonics sciences, technologies, applications and the safe use of lasers for the benefit of mankind. Laser materials processing is now a major manufacturing technology used in wide sectors of industry including aerospace, automotive, electronics, computers, mobile phones, displays, renewable energy, data storage, security and health care. It is our scientists, engineers and business entrepreneurs that have enabled the innovations and this wide spread growth in use of lasers for advanced manufacturing. LIA has provided a useful platform for the laser community to exchange ideas and develop collaborative relationships. The role of lasers and photonics in our everyday lives is becoming so important that 2015 was designated as the International Year of Light by the United Nations. The US government recently announced an investment of $600 million for a new national integrated photonic manufacturing hub (AIM Photonics) at Rochester with a government/industry joint venture.

During 2016, LIA will carry out a review of LIA membership and services, led by President-Elect Paul Denney, aiming to improve our services to the laser community. An area of growth will be seen in additive manufacturing and the wider use of ultrafast lasers within the industry. Asia, particularly China, will lead applications, while Europe and the US are expected to continue to lead innovations in the lasers, beam delivery and process monitoring, and control technologies. The job shop community in the US is a large community that LIA’s service could improve. As the Vice President of the Association of Laser Users in the UK, I have witnessed the benefit of laser job shop workshops there. Good practice could be transferred across. LIA will develop a long-term vision and strategy plan in 2016 led by past president Reinhart Poprawe, who successfully transformed the JLA as its editor-in-chief. We will also carry out a review of LIA’s finances and develop a financial plan to enable the healthy growth of the institute and its services to the laser community. Students and young people are our future. LIA will welcome students to join LIA and participate in LIA events to learn from experienced seniors and improve career opportunities. We need support from all of our members and the laser community to realize these goals and agendas. Finally, I wish a happy, healthy and prosperous New Year to all the LIA members, officers, LIA staff and everyone in the laser community.

Lin Li, President Laser Institute of America

Executive Director’s Message

Network with the Experts

During LIA’s Upcoming LAM Workshop By Michelle L. Stock

Additive manufacturing has been creating buzz for some years, and is now on the threshold of becoming mainstream. According to a PricewaterhouseCoopers survey of more than 100 manufacturing companies in 2014, 11 percent had already moved to volume production of 3D printed parts or products. With interest only increasing based on maturing technologies and processes, there has never been a better time to learn the latest about laser additive manufacturing, meet and network with experts, and benchmark laser additive manufacturing against other technologies – and no better place than LIA’s fastapproaching Laser Additive Manufacturing (LAM®) Workshop. The two-day event, held on March 2-3 in Orlando, FL, will focus on the question “why lasers?” in the burgeoning field of additive manufacturing. Through its keynotes, sessions, exhibits and networking opportunities, the workshop will answer that question and many more. For people involved in manufacturing of complex, lightweight, metal and other structural materials, LAM is a must-attend event.

LAM provides great networking opportunities with experts in the AM industry during the Exhibitor Reception

Paul Denney (Lincoln Electric) General Chair of this year’s LAM, along with his Co-Chairs Ingomar Kelbassa (Fraunhofer ILT) and Jim Sears (GE Global Research Center) have designed the program to look at how people are using additive manufacturing, and where, when and why lasers are the best solution when compared to other technologies. Denney commented, “We are hoping this year’s workshop will help attendees better understand the pros and cons of laser-based additive manufacturing over other technologies. Hopefully it will

also provide direction to those looking to improve on the status of the laser additive manufacturing and what technologies need to be developed and/or improved upon.” Users from all industries that require structural materials, such as oil and gas, aerospace, agriculture automotive, defense, marine, medical device, transportation, power generation, construction, and tool and die, can benefit from the knowledge gained by attending LAM. Whether focused on relatively small parts like medical implants and special lightweight brackets for planes, or much larger parts being made directly or that are having their surfaces modified, the program will provide an overview on the different options that are out there today to create formed parts and why you would choose each. This year’s workshop kicks off with a keynote presentation by Professor Sudarsanam Suresh Babu of The University of Tennessee at Knoxville, presenting Recent Advances in Metal Additive Manufacturing at a Manufacturing Demonstration Facility: Role of in-situ Process Monitoring, Computational Modeling, and Advanced Characterization. Following the keynote, speakers from companies who are involved in alternative technologies to laser additive manufacturing will present, including companies using gas metal arc welding (GMAW), ultrasonic welding and electron beams. With that background in mind, the program will turn to how companies select the “best” additive manufacturing process(es). The program will continue with a session on the latest in additive equipment directly from major manufacturers, including Concept Laser and Optomec Design, followed by a session on new additive approaches from both academia and industry experts, such as wire-fed additive manufacturing that can produce features the size of a match-head. The first day will be capped by an excellent opportunity to network – the Exhibitor Happy Hour Reception. The second day will address “bridging the gap” of laser additive manufacturing from research to application. Starting off, a keynote address by Professor David Bourell of The University of Texas at Austin, Director of the Laboratory for Freeform Fabrication, will discuss the current status of additive manufacturing. The morning sessions will provide insights from government, corporate and academic labs and how they are taking innovations from the lab to the factory floor. In the afternoon, the topics will shift to job shops and how they use additive manufacturing for their customers. This portion of the event will hold particular interest for those who wish to start developing prototypes and even production parts using additive manufacturing processes, but

do not know where to begin and are not ready to commit to purchasing equipment. The workshop will close with the latest in process monitoring and control, two very important aspects to developing robust manufacturing processes. Peter Baker, LIA’s executive director, is excited about this year’s workshop, stating “Now in its 8th year, LAM has become a premier event in the additive manufacturing arena. We are grateful to the contributors and sponsors who create this valuable workshop.” Of special note to those involved in medical applications, LAM General Chair Denney adds, “While LAM 2016 does not specifically have a medical focus, those in this industry sector may find the workshop of interest. Technology in sessions on new processes, monitoring-control, research facilities and equipment advances may be of benefit to those in the health care arena. LAM 2016 also provides many networking opportunities to meet with professionals involved in the next generation of processes, equipment and controls that will be used in the medical services market.” Whether you want to learn more about laser-based powderbed, powder-fed and wire-fed processing, what the latest materials are for use in these processes, or what the latest additive manufacturing trends are by job shops and industrial manufacturers, LAM 2016 is the conference you will want to attend this year.

“Welding” Nerve Cells

An Interview with Ellen Townes-Anderson BY Talia Landman

Research in the field of biomedical laser applications was a new focus at the Laser Institute of America’s (LIA’s) 34th International Congress on Applications of Lasers & Electro-Optics (ICALEO®). A fascinating presentation given by Dr. Ellen Townes-Anderson of Rutgers University, titled “‘Welding’ Nerve Cells Together with Laser Tweezers,” explored new research using optical tweezers and collaborated with the work of her late Nobel Prize-winning father and laser pioneer, Charles Townes. Townes-Anderson’s late father introduced the idea of “optical tweezers” to her in the 1990’s. She felt that she might be able to use optical tweezers to test if cells can reconnect and the ones they prefer to be partnered with. The answer to this question is vital to circuit repair. It can optimize the possibility of choosing two partners that intrinsically want to be connected. “My research focus is in trying to repair the connections between nerve cells,” explained Townes-Anderson. “All of our brain, eye and spinal cord functions depend on good communication between nerve cells.” Upon looking into the possibility of using the tweezers to repair cells, Townes-Anderson discovered they had been used to move molecules and bacteria. However, no one had yet tried to move vertebrate cells, or cells with a nucleus. Her idea peaked the interest of two companies, which provided Townes-Anderson and her team equipment for a testing site. Townes-Anderson used cells from a tiger salamander because they have the largest cells in the vertebrate kingdom. She considered that the larger cells might be more difficult to move with the tweezers and it wasn’t long before they encountered issues. When the team started to struggle with trying to move the cells, she realized what was wrong and came up with a new idea. The laser tweezers work through changes in the index of refraction, which release torque, or power, onto the cells. Townes-Anderson determined that in order to successfully move the cells, she had to create a non-adhesive substrate to place onto the culture dish so that the cells did not stick. “That’s one of the first projects we had,” Townes-Anderson explained. “[We had] to find something that the cells wouldn’t stick to, so that the small piconewtons of the laser tweezers will

be able to pick them up. We found a substance called polyHEMA which is the same stuff that they use for contact lenses. I think that makes sense because you don’t want your contact lens to stick to your cornea. It’s a very non-sticky substance and we started to coat the glass coverslip that we’re going to put the cells on with this polyHEMA. When we did that and put the cells into the culture dish, we could, in fact, pick them up. Then we were able to move them. It was very exciting.” Townes-Anderson and her team at Rutgers were able to move the largest cells in the vertebrate kingdom with laser tweezers. They picked up photoreceptive cells, photosensitive cells and what they call “second order” and “third order” neurons. Small groups starting with two cells, three cells and more were created, and led to a fascinating discovery. “We did discover that cells have intrinsic preferences. That a rod photoreceptor likes a different kind of cell than a cone photoreceptor, and that these preferences were not always what you would expect. In order words, they weren’t the cells that they might normally be in contact with. That’s the kind of information you need if you’re going to be thinking about repair. So, when you’re repairing something, it turns out that they like an unexpected partner. A novel partner.” More experiments with cells and laser tweezers included using tweezers to place cells onto micro-electro arrays (MEAs), which are electrodes connected to a box that can generate electricity and excite the cells. Neuro-scientists often use MEAs and randomly “drop” the cells onto the electrode. They don’t know what electrodes the cells are going to pair with, or the number of cells going to an individual electrode. Townes-Anderson and her team experimented with using the tweezers to carefully place cells onto electrodes and controlling the cell types each electrode head. “We were able to use some of these ideas of polyHEMA and moving [cells] with the tweezers; and indeed, we can place specific cells on top of specific electrodes, excite them, and watch them grow back together. That was another step for the use of laser tweezers with cells and we’re still working on that.” Townes-Anderson is a professor in the Department of Neurology and Neurosciences at Rutgers New Jersey Medical School in Newark, NJ.

Cymer Delivers Second Generation Solution for Reduction of Neon Consumption on ArF Light Sources Cymer, an industry leader in developing lithography light sources used by chipmakers to pattern advanced semiconductor chips, announced the availability of its second generation solution to reduce the consumption of neon gas in ArF light sources. Neon is used in the routine operation of semiconductor light sources, and has recently been subject to supply limitations. Cymer’s latest gas control technology is expected to deliver up to 75 percent reduction in neon consumption, further reducing the impact on chipmakers from neon shortages and price fluctuations

GEOMATEC Laser Scanning Optics Now Available in North America Precision Laser Scanning announces that GEOMATEC, a leading optics manufacturer in Japan, is now making its laser scanning optics available to the North American market. GEOMATEC makes high precision F-Theta lenses and beam expanders to rival the best in the world. The company has more than 50 years of experience in the optics industry but is virtually unknown outside of Japan.

This is the result of the comprehensive Neon Reduction Program started by Cymer earlier this year that led to a solution to reduce neon consumption by approximately 50 percent for ArF and 30 percent for KrF released in September which was adopted widely by customers. “Neon supply continuity and price variability have strongly impacted our customers,” said David Knowles, Vice President of Cymer Light Source. “This latest release is part of our commitment to reduce the dependence on neon by collaborating with our customers to quickly release new solutions.” For more information, visit LPW Launches New Product Line - POWDERFLOW™ LPW Technology, a market leader in the development and supply of a Total Powder Management solution into the Additive Manufacturing (AM) industry, has launched a new product line called POWDERFLOW™.

GEOMATEC F-Theta lenses are diffraction limited across the scan field, have low wave front error and are very stable in high power applications. Telecentric lenses have telecentricity of < 1.5 degrees across the scan area. These qualities are important in high precision material processing applications. Their fixed and zoom beam expanders have extremely low beam shape distortion. This is important in applications where beam shape is critical. They are easy to adjust for divergence. Common body size allows interchanging of different magnification to accommodate different sources. Visit for more information.

BLS Update All CLSOs and CMLSOs with certification maintenance (CM) cycles that ended December 31, 2015 who have not recertified – Contact the BLS office today to avoid losing your active status. In accordance with the CLSO and CMLSO Policies & Procedures manuals, CM worksheets with supporting documentation and recertification fees must have been postmarked by January 31 following the end of the 3-year certification cycle. The consequence of not recertifying by this date is “Inactive Status,” which is loss of the use of designation. To restore status, CM worksheets accompanied with appropriate recertification and late fees will be accepted up to and including May 31. After that time, it will be necessary to retake the exam to become active again.

• Magazine or newsletter publications (print or online) = ½ point per article • Participation on a laser safety related committee outside of daily job responsibilities, 1 point per year = 3 points total • Presentations at laser safety professional conferences, workshops or meetings = ½ point per presentation For questions related to certification maintenance or assistance in completing the CM worksheet, please contact the BLS at +1.407.985.3810 or email

For many CMLSOs in particular, coming up with CM points seems a daunting task as oftentimes laser safety is only a fraction of the job. To add to the confusion, one CEU does not equal one CM point; maintaining licensure is not equivalent to renewing laser safety certification. In essence, documenting professional development activities, e.g., continuing education is the goal of the CM point renewal process. A breakdown of CM worksheet categories may benefit those trying to submit. Remember the requirement is a minimum of 10 CM points over the 3-year cycle: • Job experience, 1 point per year = 3 points total • Membership in a professional society, 1 point per year of membership = 3 points total, e.g., LIA, AORN, ASLMS, see the BLS website for approved organizations

Certification for Medical Laser Safety Officers Providing Professionals a Means for Improvement in the Practice of Laser Safety

• Attendance at a laser safety or applications conference, 1 point per 6-8 hour day e.g., attendance at the International Laser Safety Conference (ILSC®) = 1 point per day. Full conference attendance, i.e., Monday-Thursday = 4 points total Attendance at AORN does not equal one point per day; only sessions related to laser safety can be counted toward BLS certification maintenance, points are determined based on session duration. • Refresher training or in-service training, point values are time-dependent, i.e., how long did the training last? • Publication of peer-reviewed articles = 1 point per article

In addition, the organizations will focus on sharing information on laser regulations and standards, bioeffects lasers have on the eyes and skin, laser control measures and laser safety program administration.

Departments of Labor and Justice Launch Initiative to Cooperate on Investigation and Prosecution of Workplace Safety Violation The Department of Labor and the Department of Justice have established a new initiative to prevent and deter crimes that jeopardize the lives and health of workers. The initiative strengthens the ability of the two departments to investigate and prosecute employers who fail to provide a safe workplace for their employees. Deputy Secretary of Labor Chris Lu joined Deputy Attorney General Sally Yates in signing the agreement during a ceremony at the Dept. of Justice on Dec. 17.

and the US Attorney’s Offices to work with the Department of Labor’s Occupational Safety and Health Administration, Mine Safety and Health Administration, and Wage and Hour Division to investigate and prosecute worker endangerment violations. The worker safety statutes generally provide for only misdemeanor penalties, and the new initiative will encourage them to use the federal criminal and penal code and environmental offenses, which often occur in conjunction with worker safety crimes, to enhance penalties and increase deterrence.

Identifying Residual Stresses in Laser Welds by Fatigue Crack Growth Acceleration Measurement By Jesper Sundqvist, Alexander F. H. Kaplan, Jan Granström, Karl-Gustaf Sundin, Markku Keskitalo, Kari Mäntyjärvi and Xiaobo Ren

During laser welding, residual stresses are thermally induced. They can have strong impact on the fatigue behavior and fatigue life. A standardized measurement method for the fatigue crack growth rate was expanded to identify residual stress along the cracking path. The second derivative of the measured crack opening and in turn the crack acceleration corresponded well with distinct acceleration maxima and minima and accordingly with tensile and compressive stress, as was basically proven by numerical simulation. The method is simple and extendable. It provides valuable information, as was demonstrated for various situations.
